TRS-80 Model 1 Level II with FreHD/Quinnterface Combo Box TRSVID @RoyAntaw

Uploaded February 2021 | Updated September 2026, 2 weeks ago

I have successfully flashed a new PIC18F4620-I/P MicroChip microcontroller with the FreHD_3.00.hex firmware required for TRSVID software and then replaced the original FreHD microcontroller which was flashed with version 2.50 firmware (for safekeeping). The Video and Audio seen in this video were generated on the TRS-80 Model 1 using LDOS and TRSVID software.
